OIL-CUP.

Be it known that I, STEPHEN I. FEKETE, a subject of the King of'Hung/gary, residing at Detroit, county of Wayne, State of Michigan,have invented a certain new and useful Improvement in Oil-Cups, of whichthe following is aspecification, reference being had .therein to theaccompanying drawings.

My invention has for its object a new and improved oil cup to be usedparticularly on motor vehiclesfor lubricating moving parts, such forinstance, as spring shackle bolts andthe like. Great difiiculty has beeneX- perienced in the past with lubrication of such parts, because theoperators of vehicles find the work ofreiilling the lubricating devicesdirty.v and inconvenient, vand therefore, neglect it.r The workof'frefilling a grease cup is particularly inconvenient and likely'tofbe neglected. Furthermore, the capsof grease cups are frequentlylost owing to the vvibration ofy thevehicle which causes them tounscrelw.` Aserious objection to oil cups as distinguished fromVgrease'cups is that grit works into the oil cup and is carried by the'-o il into the bearing, thus'causing the bearing to wear which is thevery thing which the lubricant is intended to prevent.

- Furthermore,- theoil is shaken out and lost when traveling roughroads. One object of my invention is to provide an oil cup -Vof lar ecapacity so thatit will Vrequire filling' on y once Vor twice during fthe season, that will retain the oil put into 35 it Aand will furnish'tothe wearing parts oil which is entirely-free from dust or grit.V

The oil cup embodying my invention is intended particularly for use ineither avertical or horizontal position without change Aofconstruction-...This is avgre'atradvantage, 4as ordinary oil cups do notwork as well on .horizontal"bolts, as on vertical ones.

`The invention will -be'fully understood 'from the following descriptionwhen taken in connection with the 'ac'comp'anyingvdrawings, andthefno'velfeatures thereof will'be pointed out and clearly defined inthe claims atv the close of this' specification. vIn the drawings,

Figure 1 is aside elevation of an oil cup embodying my invention,

vthe saine being'shown inv the position which is Voccupies lwhen'`applied to a horizontal bolt, such for `instance as a spring shacklebolt. Y Y 1 is sometimes necessary.

oil in the cup when the cup is in the several U l,

positions shown.

. Referring now to the drawings, at A is shown the casing preferably`made in two parts 11'I and 12 soldered together as shown at 13. rlheIpart 11 is securedv to a screw- ,1 l

threaded shank 111, which engages the bolt to be vlubrica-ted,theshankll having a wrench-receiving portion 15. The vother part 12 of thecasing is provided with an oilinlet hole 16 closed 'by some suitableclosure, as for instance, a ball 17 held in contact with theedges of thehole by a spring 18. When this form of-closure-is employed, Athe edge ofthe casing surrounding the hole 1'6 is cupped, as shown at 19, to form aseat for the ball 17, and may bef 'flared on the outside as'shown -at26. This flaring renders it easier for the operator to iind the' oilinlet hole with 'the spout of the oil can when the cup is placedl in aninconvenient position as Any other wellknown type 'of closurevfor thehole may be employed.

Surrounding the' hole 16 and extending tion tube 20. This oilintroduction tube is provided with a pair ofv ears 21 which support abaille or trap 22 which is a-V dishshaped member. This baiile is of adiameter larger thaty the greatest diameter of the oil introduction tube2O and is located between the inner-end of the oil introduction tube andthe outlet hole with its open end 23 to the right of the inner end ofthe oil introduction tube when the parts arein the position shown inFig. 2. 'In other words the ybaffle 22 overlaps the oil introductiontube 20, and being of greater diameter than said tube its sidewall isspaced apart from said tube so that said baiile loosely encircles saidtube, so as to leave a passage for oil. The

linwardly therethrough is an oil introducc,

position. t 25 is a disheshaped screen for locating and holding thestrands 6 vof wicking, ltwisted. together and aroundv a wire 27 by meansof which thewicking can be conveniently inserted in the central hole inthe bolt which is to be lubricated by the use'v of the oil cup. Thiswire 27 is conveniently 11', as will be understood fromV Figs. 2, 3v

and 5.

The casing ismade of relatively large diameter vso that it will containas much oil as-possible, and-'there `is 'a freeI space for oilbetweenthe battle land the screen'. When in vertical position with the'oil opening Y upward the'foil cup-can be-filled up to the bottom oftheoil introduction tube 20; when lin horizontal position, as shown inFigs. 1 land 2, itcan be filled up tothe lower edge of the hole 16. Thetube 2O extends into the center off-the oil cup soy thatv the cup willstill" be half vfull with the filler pointed downward; Thus itk can belseen that the cup; can always be at least haltl fill'ed.-1 Tlievtube 2Oandv b'ailie' v22 prevent oil once infrom being shakenout evenfshouldthe ball 17 be off its seat.- AsE the wicking operates bycapillaryattraction, all danger osediment reaching the moving parts is completelyeliminated whilethe screen holds the wicks in place and at the same timeallows the oil to reach them. y Y

Itwill be-noted that thewicking closely lills the oil outlet afforded bythetube or shank 14, and thus acts as-a iilter for the oil topreventsediment yor grit-from passing to the bearing to be lubricated.`

The oil introduction tube 20surrounding the-oil inlet hole is a veryimportant lfeature of my invention. YI ind lin actual practice thatthe-oil cup embodying my invention Vis practically oil tight in anyposition even though-the balile22 'and the valve 17. are omitted.- Itthe oil cup is placed `invertical position with the oil inlet hole atthe vtop as shown'inFig, the oilY introduction tube 20'preventssplashing resulting from. either horizontal or verticall movements ofthevehicle to which yitis-attached. T the oil cup is placed in avertical positionwith the oil holel down asfshown in Fig'i'?, theYcupcan be filled,- nearly to thetop ofthe'tube and 'no'oilfwilllescapeVVhe'nf-the oil cup is placed in vhorizontal:posit-ion asfshown-.in Fig.8, theoil introduction=.tube: prevents the escapeof oi-l' due to thelformation of a wave caused bye-horizontal; movements. ofthe vehiclezlWhen placed in inclined position (see .Figf 9) L the oil!introduetiontubeprevents loss of oil from splashing' as shown. The

valve 17 serves chiefly to prevent the enof the wicks will dip in theoil inthe bottom of the oil 'cup when the oil cup is placed inhorizontal .position regardless of the position axially which the oilcup assumes. This is an important feature becausevit makes it possibleto screw the stem 14 tightly into the shackleboltor otherpart'to be`lubricated and no attention need belpaidutothe position which the oilcup assumes when the parts are tight. In this respect, the oil cup is agreat improvement over. the Voil cups of -thetype which must be placedin some predetermined position.
